JavaScript - get array element fulfilling a condition

Question

I\'m learning JavaScript using W3C and I didn\'t find an answer to this question.

I\'m trying to make some manipulations on array elements which fulfill some conditi

Answer 1

You can use Array.prototype.find, wich does exactly what you want, returns the first element fullfilling the condition. Example:

> ([4, {a:7}, 7, {a:5, k:'r'}, 8]).find(o => o.a == 5)

{a:5, k:'r'}
